The ratio of Holly's age to that her aunt is 4:9. When holly was born her aunt was 15 years old. How old is holly's aunt now?

Lyrx [107]

Answer:

27 years

Step-by-step explanation:

Let Holly's age be h and Aunt's age be a. We can setup 2 equations and solve.

1. $\frac{h}{a}=\frac{4}{9}$

2. a - 15 = h

We can plug in equation 2 into equation 1 to solve for aunt's age:

$\frac{h}{a}=\frac{4}{9}\\\frac{a-15}{a}=\frac{4}{9}\\9(a-15)=4a\\9a-135=4a\\5a=135\\a=\frac{135}{5}=27$

Holly's aunt's age is 27

Eight years ago, Clyde was 7 years old. Which equation represents Clyde age now?

vichka [17]

Answer:

Step-by-step explanation:

Clyde's present age is 7+8, because he has aged 8 years since he was 7.

So, the equation would be C=7+8.

However, that equation isn't listed so you need to move some numbers around.

If you subtract 8 from both sides of the equation C=7+8, you get C-8=7, which is D.

Hope this helps! :)
